You seemed to have a good grasp of "Periodic Table" and "Atomic Structure". Congrats! PS: look forward to more of your participation, as this is the best form of learning methodology Cheers, Sean Chua Master Trainer & Author WINNERS Education Group “Experience Learning with A Difference” Hi Kwee,

Max number of valence electrons is 2 for the 1st period, ONLY. 8 for the rest. Proton number will keep increasing, but the valence electron number will not. i.e. from proton number 1 to 12, the configuration is (1; 2; 2,1; 2,2; 2,3 ... 2,8; 2,8,1; 2,8,2) meaning, it will go from 1 to 2, back to 1, go up to 8, go back to 1 and increase by 1 again. Hence B is the answer. Ans is B.
